Profile sections for plate-like composite elements

Abstract

The invention concerns profile sections for reinforcing or finishing the edges of plate-like composite elements, said sections comprising a core layer (31) and two cover layers (11, 21). The invention further concerns composite elements produced thereby and a method of producing these composite elements. The profile sections consist of at least two parallel legs (1, 2) and a connection web (4) and comprise an abutment surface (3) for the core layer (31). Disposed between the edges (5, 6) of the abutment surface (3) and the connection web (4) are open channels (7, 8) through which the air located between the cover layers (11, 21) and the core layer (31) and/or the profile section legs when the composite element is bonded can escape such that a bubble-free bonded connection is attained over the entire surface.
